Please help!

I'm trying to find a manhwa that the fl went back in time after dying of disease. All I remember about it was before she died she asked her husband to divorce her after all the neglect she faced. However, she didn't know her husband actually turned back time with their child who was a magician (?) Because he regretted going to war so much. He loved her all along but never communicated it. Lastly the thing I remember the most was they started selling wigs as a plot point cuz their house was being cheated out of money and they were poor coz her husband was just a normal soldier who got titled a noble. Thank you for any help!!!
